Question

this biome has fertile soil and is being converted to farmland in the midwest. temperate forest tropical rainforest chaparral grassland

Explanation:

Grasslands have deep, fertile soil that is ideal for agriculture. In the Midwest of the United States, much of the original grassland biome (such as the prairies) has been converted to farmland. Temperate forests have soil that is less fertile for large - scale farming compared to grasslands. Tropical rainforests have soil that is often nutrient - poor (because nutrients are quickly recycled in the lush vegetation). Chaparral has thin, rocky soil that is not as conducive to large - scale farming as grassland soil.

Answer:

grassland
